BEN CLIFFORD BLACKMON, OF DALLAS, TEXAS.

The present invention relates to a machine for assisting a Workman 1nthe construction of matrices used in newspapers.

.A matrix consists of a heavy base, two thinner pieces or sheets, andthree sheets of tissue, pasted together. One man, in the ordinary methodof making matrices stands at each end of a small table. One man arrangesthe sheets while the other spreads the paste between the sheets androlls out each sheet as it is applied to the base sheet. The principalobject of the present invention is to do away with the man now necessaryto arrange the sheets and to allow one man to make a matrix in less timethan by the ordinary method outlined above.

Another important object of the invention is the construction ofamachine of this nature so that the same will be exceedingly simple,strong, durable, easy to manipulate, efficient and reliable in itsoperation, and otherwise well adapted to the purpose for which it isdesigned.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing 2- Figure 1 is a top plan View of the machine embodyingthe features of my invention.

Figure 2 is a side elevation thereof.

Figure 3 is a front elevation thereof, and

Figure a is an enlarged detail vertical section through the forwardportion of the movable truck. 1

Referring to the drawing in detail it will be seen that numerals 5designate the four legs of the machine which are preferably mounted oncasters 6, and are braced by a rectangular frame 7, or in any othersuitable manner. A frame 8 is supported at the upper ends of the legs 5and has mounted thereon a sheet metal top 9. A pair of inclined arms 10project forwardly from the frame 8 below the top 9, for the purpose ofsupporting a roller 11 in a handy position as will be more apparent asthe description proceeds. A pair of beams 12 are attached to the legs 5and extend rearwardly therefrom and are inclined upwardly. Tracks 13 aremounted on the upper edges of these Application filed October 12, 1925.

beams 12. One beam is located to each side of the machine. Stops 14 areattached to the beams 12 and extend above the tracks 13 between the legs5, as is shown to advantage in Figure 2. A pair of posts 15 rise fromthe beams 12 to the rear of the rear legs 5, and support at their upperends a shelf 16 which is inclined forwardly and downwardly. A truck 17is supported on legs 18 and 19. The legs 18 are at the rear of the truckand are slightly longer than the legs 19 so that the truck 17 isinclined forwardly and downwardly. Grooved wheels 20 are journaled atthe lower ends of the legs 18 and 19 for riding on the tracks 13. A back21 rises from the rear edge of the truck 17 and brackets 22 projectforwardly therefrom for receiving screws 24 for clamping plate 25 on thetruck 17. Brackets 26 project forwardly from the truck and havejournaled therebetween a roller 27 Frames 28 rise from. the forward endof the truck 17 and slidably support journal blocks 29 in which isjournaled a. roller 30. Brackets 31 are disposed forwardly of the frontlegs 19, and rise above the plate 9. A catch 33 is pivoted as at 34 toone beam 12, and is adapted to engage one of the forward legs 19 forholding the truck in its rearward position as shown in Figure 2. A link35 is pivotally engaged. with the catch 33 and with atreadle 36 pivotedin the frame 7. When the operator steps on the treadle 36, the catch 33is released, thereby allowing the truck to roll forwardly on theinclined tracks 13 until the front rollers 20 engage the stops 1 1. Ashelf 37 extends from the right hand side of the machine and is adaptedto support a paste pot 38. A drain lip 39 inclines downwardly from theright hand edge of the top 9 over the pot 38.

In using the machine, only one worker is required. The heavy base sheetsare laid out on the shelf 16 at the top of the machine. The thin sheetsare placed on the truck 17. One of the heavy base sheets is taken fromthe shelf 16 by the workman and placed on the top 9. The paste isapplied to this sheet. The treadle 36 is then operated for releasing thetruck 17 which moves forwardly. The operator then removes one of thethin sheets from the truck between the rollers 30 and 27, and places theforward edge thereof evenly with the forward edge of the pasted basesheets. The roller 11 is then brought into play being lifted from thearms 10 and rolled rearwardly. As this roller moves rearwardly itengages the bracket 31 and pushes the truck 1'? to its rear position,the

catch 31 engaging it in this rear position as is obvious. The secondthin sheet is placed on the first thin sheet in a similar manner as willbe obvious. The workman then removes the remainingthin sheets from thetruclr and places in place of them the tissue sheets, and thesetissuesheets are applied by the same operations as described incident tothe thin sheets, By actual experience it has been found that one man canmake the matriceswitli this machine much more rapidly and etficientlythan can two workmen using the ordinary method mentioned above.

It is thought that the construction, opera tion,"and advantages of theinvention will now be apparent without a more detailed descriptionthereof. The present embodiment of the invention has been disclosedmerely byway of example since in actual practice it attains the featuresof advantage enumerated as desirable in the statement of the inventionand the above description. It will be apparent that this embodiment ofthe invention possesses superior compactness and convenience both fromthe standpoint of structure and operation.
